Tax relief for caregivers

Being the primary caregiver for a parent with Alzheimer’s, dementia, or mental deficiency due to an accident should allow that caregiver to claim the parent as a dependent. I had to bathe, clothe, and feed my mother who required 24 hour supervision for 5 years. A tax break for caregivers would also be a huge benefit. The IRS allows a one time deduction of around $2000 for in home health care, I was paying $400 a week out of pocket for someone to stay with my mother so I could keep my job. A lot more that $2000 over 5 years.
Thank you for taking time to consider this.
